The newest multifamily building to be developed near Nationals Park in Southeast D.C. isn’t open yet, but it’s already nearly fully leased.

Representatives for Brookfield Properties, Urban Atlantic and the D.C. Housing Authority are slated to hold a ceremonial grand opening Thursday for the Harlow, a 179-unit building at 1100 Second Place SE. Leasing began in March, and about 95% of the project’s units are now spoken for.

The project’s quick lease-up suggests demand for rental units in the Capitol Riverfront Business Improvement District remains strong amid a wave of new supply springing up around Nats Park, where the home team moved one game closer Monday night to their first World Series appearance.

“We were able to do over 20 units a month essentially between March and September of this year, so it was incredibly fast to be able to get it done,” said Caroline Kenney, managing director for public-private ventures at Urban Atlantic.
